Resiliency Improvement of Cyber-Dependent Distribution Network Using Mobile Energy Storage Systems

The need for reliable restoring solutions, particularly during natural disasters, has highlighted the importance of enhancing the resiliency of power distribution networks (PDNs). This work focuses on achieving a resilient PDN by restoring more loads through network reconfiguration in the system with renewable energy resources (RES) and mobile energy storage systems (MESS). The status of the cyber (communication) network greatly influences the restoration process of the PDN in terms of the communication between the buses and the central controller. Therefore the restoration problem of the PDN has to consider the status of the communication network. This work focuses on formulating the restoration problem of such cyber-dependent PDN. A novel cyber-dependent restoration problem is proposed as a mixed integer linear programming (MILP) optimization problem by utilizing MESS, RESs, and network reconfiguration for efficient restoration within the PDN. The proposed method of resiliency improvement is tested and validated on the standard IEEE 33 bus system in MATLAB.
